regions of both hemispheres. From all these sources he was constantly 
receiving at Knowsley, so many new and rare living animals of every sort, 
that the Knowsley Menagerie was, at its dispersal in 1851, celebrated, far 
and wide, as one of the largest and 
finest zoological collections in Ku- 
rope. This Vivarium was splendidly 
housed in various parts of the 
grounds ; in commodious sheds and 
sheltered paddocks, as well as by the 
margin of artificial lakes and in spac- 
ious Aviaries. In the last there 
appear to have been, of Parrots alone, 
as many as one hundred and four- 
teen specimens, belonging to sixty 
nine species, alive on the Ist of 
September, 1848. 
All the animals that died in the 
Menagerie were carefully preserved, 
either mounted or in skin; the very 
large specimens being presented to 
the National Collection, while the 
rest were added to Lord Derby’s 
private museum. To the increase 
of this part also of his collection, 
great attention was paid by Lord 
Derby, and it grew rapidly through 
his constant purchases as well as 
by the specimens sent to him, in large numbers, by his foreign correspon- 
dents, by distinguished travellers, and by collectors, and not least as the 
result of the expeditions he equipped. Many of these acquisitions were 
naturally the types of species new to science, and were described either by 
Lord Derby, or by naturalists to whom he entrusted them for that purpose. 
Not a few, however, remained for years in his cabinets, apparently 
unrecognised as unknown to science, and were described from examples, 
in other collections, obtained long 
subsequently. So, although the 
original specimens of several spec- 
ies are in the collection, they have 
unfortunately missed being the 
types. This entire museum, con- 
taining many thousands of speci- 
mens, it was, which, when handed 
over to the city by the Fourteenth 
Earl of Derby in 1851, formed the 
nucleus of our Natural History De- 
partment, whose treasures, many 
of them of great historical interest, 
are as yet but very imperfectly 
known outside the Museum. 
The Mayer Museum, in like man- 
ner, commemorates, in its name, 
the liberality and public spirit of 
Joseph Mayer, F.S.A., a goldsmith 
of Liverpool, who presented to the 
city, during his life-time, in 1867, 
a collection but little less valuable oe 
and extensive than Lord Derby’s. JosepH Mayer, F.S.A.
